“…The present study was carried out to investigate the effect of 28-homobrassinolide (28-HBL) on the protein content as well as activities of antioxidant enzymes viz., glutathione-s-transferase (GST) and polyphenol oxidase (PPO) in radish plants grown under Cadmium (Cd) and Mercury (Hg) metal stress. MATERIALS AND METHODS: Shoots of 60 and 90 days old radish plants, grown under Cd and Hg metal stress (0, 0.5, 1.0, 1.5 mM) and given the presowing treatment of 28-HBL (0, 10(-7), 10(-9), 10(-11) M) to seeds for 8 h, were analyzed for protein content and GST and PPO enzyme activities. …”

“…Results showed that Cd had no significant impact on biomass production while Ni and the combination of both metals drastically affected plant development. Cadmium and Ni concentrations in tissues and xylem sap were higher in plants subjected to individual metal application than those subjected to the combined effect of Cd and Ni suggesting a possible competition between these metals for absorption. …”
